MTC Motorsport BMW M140i Intake Hose and Alloy Machined AFM Housing Kit with Heat Shield and RamAir Filter. This hose is handmade from 6 layers of silicone and is fluoro lined to prevent discolouration. It provides a much sharper throttle response and massive improvement on torque. We have seen some surprising power gains with just this installed alone. Around 8-10whp to be precise. It also sounds great with some great turbo noise. This kit will fit the following models with B58 engine. 6-ply intake hose (very strong). Aluminium machined AFM housing and bracket. 55 Tuning custom made B58 heat shield. Bolts and clamps needed to install. Fitting should take no longer than 10-15 minutes and is easy to do.
